Description

scsi: target: Fix NULL pointer dereference in core_scsi3_decode_spec_i_port()

In the Linux kernel, the following vulnerability has been resolved:

scsi: target: Fix NULL pointer dereference in core_scsi3_decode_spec_i_port()

The function core_scsi3_decode_spec_i_port(), in its error code path,

unconditionally calls core_scsi3_lunacl_undepend_item() passing the

dest_se_deve pointer, which may be NULL.

This can lead to a NULL pointer dereference if dest_se_deve remains

unset.

SPC-3 PR SPEC_I_PT: Unable to locate dest_tpg

Unable to handle kernel paging request at virtual address dfff800000000012

Call trace:

core_scsi3_lunacl_undepend_item+0x2c/0xf0 [target_core_mod] (P)

core_scsi3_decode_spec_i_port+0x120c/0x1c30 [target_core_mod]

core_scsi3_emulate_pro_register+0x6b8/0xcd8 [target_core_mod]

target_scsi3_emulate_pr_out+0x56c/0x840 [target_core_mod]

Fix this by adding a NULL check before calling

core_scsi3_lunacl_undepend_item()

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
